The precise nature of my invention evi ili be olearlyeap went from the following escription. en claim? "token in connection orming part of this -the eccolopen i oig drawinge---Figore I.

dump door and its opmtmg mechanism, the door'be'mg in o n position. Fig. 2' is a view similar to 1g. 1, but showing the door oio'sed. Fig. 3 is a detail ofmeens for ro tating the shaft. Fig. 4 ise transverse section of a car having my invention applied thereto.

- My invention is applio'dfio thet close of cars in v*vihioh dump doors hinged at; or adjacent the longitudinal meziioo line of flee oar are supportedfand operate iroin closed to open osition end vice veioe$y mean; of e dlsp eceable shaft or hog toolm1 311 Thls shaft rests upon mcimed tracks beneath the floor level, 'anfd occu ies epoibion between said hooks and the lunged floor sections or dump f .v referably, the lower sideeof the doors are also pro vided with cooperating ii'xieiihed irecke. The shaft or disphceable sill, beiogdooated those fixed io the car m1derfmme,.operebes when moved from the center towerd file side oi the car to raise the doors, and when moved in the opposite direction permits the doors to drop to open position.

My invention pertains to the means for im ertim the outward and inward moveusual inclined track 63 is prov ic ed at each edge of each door, these tracks nemg ee Speeifiootipn of Miter fo esee. .mnagu one amen 1 1,-1eo1, eoa; 3'6; eemoa. meeme Septomnoz was. gone: mg eaapuz.

It is apparent that my invention is limited to the precise structure above deseribei one? illustrated in the drawings, but embraces broadly the idea of reciprocating a not door operating shaft by means woolwing bethe horizontal portion 35 caused to reciprocate bodily on said support.

times, means to rotate said shaft, and means i j acent its free edge respectively, whereby cooperating with said shaft and with the door to cause the said shaft toreciprocate bodily when rotated.

2.1m a dump car, a door, an operating shaft adapted to support the doorat all times, means to rotate said shaft, and a flexible member connected to said shaft and to the door, whereby when the shaft is rotated the flexible member winds thereon and imparts bodily movement thereto.

3. In a dump car, a door, an operating shaft adapted to supportithe door at all times, means to rotate; said shaft and a chain connected to said shaft and to the door, whereby when the shaft is rotated the chain winds thereon and imparts bodily movement thereto.

4. In a dump car, a door, an operatin shaft adapted to support the door at al times, a support for said shaft, and means cooperating with said shaft and with the door to cause said shaft td reciprocate bodily on said support when rotated.

5. In a dump car, a door, an operating shaft adapted. to support the door at all times, an inclined sup ort for said shaft, and means cooperatingivith said shaft and with the door to causesaid shaft to reciprocate bodily on said support when rota'ted.

6. In a dump car, a door, an inclined support, a shaft coperating at all times with said door and said support, and means operatively connected to said door and said shaft, whereby when said shaft is rotated it is 7. In a dump car, a door having an inclinedtrack on the under side thereof, an inclined support secured to the car frame, a shaft cooperating with said track and said sup ort, and means operativelyconnected to said door and said shaft, whereby when the shaft is rotated "it is caused to reciprocate bodil on said-support. a

said shaft being movable along said track to ,bpen and close said door, means for rotating said shaft, and a chain connected at its ends to said shaft and door respectively.

9. In a dump car, a hinged floor section,

a track beneath the floor level, said track slopin downwardly toward the hinged side of said door, a rotatable and bodily H102 LlJlE shaft between said track and door, means for rotating said shaft, and a chain secured at/its ends-to said shaft and to said door adthe rotation'of'the shaft causes the chain to wind thereon and to move said shaft up the inclined track to close the door.

10. In a dump car, a hinged dump door,

an inclined track beneath said door and extending downwardly from the free edge of 65.

said door, a supporting shaft between said track anddoor and movable along said track to govern the position of said door, a chain attached at one end to said shaft and at the a other end to said door adjacent its free edge,

and means for rotating said shaft.

13. In a dum car, a hin ed floor section, an inwardly and downwardl secured to the car underframe beneath the floor, a movable shaft'or sill supported' on said track and adapted to reciprocate trans- 1 versely of the car to operate the door between its extreme open and closed positions,

a chain secured at one end adjacent the outer edge of the door and at the other end to the shaft, and means to rotate said shaft, the winding and unwinding of the chain on the shaft respectively causing and permitting said shaft to roll on the track, and the length of'the chain being so proportioned that when the shaft is in its extreme inner and lower position the chain will be partially wound on said shaft, the chain leaving the shaft at .the lower side thereof;
